Conducted researches were aimed to determine suitability of soils in the wider city area of Ogulin for growing vegetable crops. For that purpose are defined physical and chemical characteristics of the soil on 250 hectares in 2014.
Based on the conducted field and laboratory research it was established that investigated soils belong to the class of automorphic soils with profile A- (B) -C. The share of clay particles increases with depth, indicating a leaching process. It is a distric brown soils, leached with a deep humus accumulative layer.
From the results of the mechanical analysis of the trinketsit is established that they are homogeneous soils, silty loam to silty clay loam texture. Dominated by fractions of fine and coarse powder and clay fractions. A high proportion of dust and clay particles makes this low permeability soils and prone to compaction.
From the results of chemical analyzess showed that it is a heterogeneous soil very acidic to slightly acid reaction in the upper layers of soils, and it is necessary to implement calcification. Soils are moderately to richly supplied with humus and total nitrogen. The amount of humus and total nitrogen with depth of soils decreases.
Soils supply of plant available phosphorus ranges in very wide range of very poor to the rich supply. In general, the supply of plant available phosphorus in soils is poor in most parts of the surface, therefore the fertilization with phosphorus mineral fertilizers is the unavoidable agrochemical measure, while the supply of plant available potassium is good to rich.
